根据北美 L. 分散菌群的分类学修订讨论了 Lecanora 的两个物种的身份。最近在 GOET 发现的 L. fl otviana Spreng. 的原始材料在形态和化学含量上与目前已知的该名称实体不同，并且不属于 L. 分散组，而是一个鲜为人知的物种。因此，L. fl otviana 被排除在该组之外，而 L. semipallida H. Magn. 则被排除在该组之外。被证明是 L. 分散菌群中常见、分布广泛的成员的正确名称，该成员迄今称为 L. fl otoviana (auct. non Spreng.)。 Lecanora xanthostoma Cl. Roux被认为与L. semipallida同种，因此被简化为同义词。
The identity of two species of Lecanora is discussed in accordance with a taxonomic revision of the L. dispersa group in North America. Original material of L. fl otoviana Spreng., recently discovered at GOET, differs in morphology and chemical content from the entity currently known by that name, and does not belong to the L. dispersa group but is a little-understood species. Consequently, L. fl otoviana is excluded from the group, and L. semipallida H. Magn. is shown to be the correct name for the common, widespread member of the L. dispersa group hitherto known as L. fl otoviana (auct. non Spreng.). Lecanora xanthostoma Cl. Roux is considered to be conspecifi c with L. semipallida and is therefore reduced to synonymy.
